The MC Hand is not waterproof
Do not allow water to enter the cosmetic glove or inner hand shell. To minimize incidental moisture damage
such as rain, or cleaning the hand with a damp cloth, maintain an intact cosmetic glove and inner hand shell.
Damage to either, will allow moisture into the mechanism and cause damage. If water or other liquid should
enter the hand, remove the hand at the quick disconnect (or turn the hand o if there is no quick disconnect)
and take it to your prosthetist for disassembly and inspection.
Flammable Gases
Caution should be used when operating the hand around ammable gases. The hand utilizes an electric
motor that can ignite volatile gases.
Do not bend ngertips
While the MC Hand is robust, body weight represents a great deal of force. Do not apply full body weight on
the nger or thumb tips. Additionally, a fall with the force directed to the ngertips could cause damage. If
the ngertips do become bent or out of alignment, remove the cosmetic glove and inner hand shell. If the
index nger, middle nger and/or thumb are badly bent, broken, or out of alignment, return the hand to
Motion Control for replacement of ngers.
Safety Release
Do not force the ngers and/or thumb opened or closed. This will result in serious damage to the device.
The safety release will allow easy opening and closing of the hand. If the release mechanism does not allow
motion, the device requires service by Motion Control.
Repairs or Alterations
Do not attempt to repair or alter any of the mechanical or electronic components of the MC Hand. This will
likely cause damage, additional repairs, and void the warranty.
Safety Caution
Use caution when using this device in situations where injury to yourself or others may occur. These include
but are not limited to activities such as driving, operating heavy machinery, or any activity where injury
may occur. Conditions such as a low or dead battery, loss of electrode contact, or mechanical/electrical
malfunction (and others) may cause the device to behave dierently than expected.
Special Precautions
Three Position Switch
The MC Hand has a three position sliding switch
located in the middle of the back of the hand. On the
palm side, it is located at the base of the thumb. With
the switch pushed all the way toward the back of the
hand, the hand is OFF. Pushing from the back of the
hand towards the palm, the rst click turns the hand
ON. Pushing completely toward the palm is the SAFETY
RELEASE position, releasing the ngers. In the Safety
Release position, the hand is also turned OFF.
